my new girlfriend's family is jewish and inviting me over for a kosher dinner. i dont like vegetarian food.

Kosher does NOT mean "meatless" but, has more to do with the way the food is prepared...in line with Jewish tradition.

But let's say the g/f's family were Vegetarian...you couldn't "sacrifice" one meal not having meat?

You would actually slap a steak on their counter and proclaim "I like meat so, even though you don't, here's what I would like for dinner so, please cook this steak for me."

Rather absurd I'd say.

Since everyone has addressed the kosher aspect accurately (I'm an agnostic Jew myself), I'll address the vegetarian issue. You don't like spaghetti with marinara sauce? You won't eat a salad? You don't like soups unless they have meat stock or chunks of meat? You don't like ANYTHING unless it has something meaty in it? You won't eat a pizza unless it has pieces of meat splattered all over it?

If you don't think you'll like the dinner, you can always have a snack beforehand so you won't starve if the food isn't to your liking. And if you do like the food, you can have a fairly good-sized dinner. But depending on how observant her family is, you CANNOT bring your own non-kosher slab o' cow into a kosher household.

Are you assuming that kosher & vegetraian necessarily mean the same thing,kosher is food prepared from start to finish by a set of rules set out by jewish law ,not all jewish families adhere to these strict rules.

Accepting an invitaion to a meal ,generally means you accept what your host has cooked ,even if it is not totally to your liking,one meal that is different in taste or style of preperation does not hurt ,You don't want to hurt your gfs or her families feelings ,do you ?.

Is it a kosher dinner or a vegetarian dinner? They are two different things. Kosher does not mean meatless.

But, even if it is meatless, do NOT take your own meat! That would be very very insulting to your hosts!

Either be prepared to eat the dinner they serve or decline the invitation!

Kosher does not mean meatless, it refers to the way the food is prepared. Unless they are vegetarian as well, they should be serving some type of meat.

Kosher doesn't mean "vegetarian". The family might not even be "kosher".

Even if they are vegetarian --- suck it up. And by the way, Jewish people value education and are very well-read. So if you show yourself to be foolish as you did here, they will have their daughter dump you.

Kosher and vegetarian aren't the same thing. You should be more worried about sounding unintelligent to her parents, than about the food.

Whatever you do, don't fly a plane over their house, Huckleberry.

Do not bring your own food, especially meat. Kosher doesn't always mean vegetarian either. In Kosher cooking you use clean food, and have separate utensils for your meat and vegetables. Bringing in unclean meat would contaminate anything it came in contact with (according to kosher rules). All that, aside from being rude. Imagine bringing a cheeseburger to your mother's Thanksgiving dinner, it's saying "I know I'm not going to like what you made" and is insulting.

DO NOT bring meat with you. They won't be able to eat, because your meat is unclean. Secondly, kosher doesn't meat vegetarian. You know that, right?

You might also want to research etiquette, unless you want her parents to make her dump you.

kosher does not mean vegetarian if you want, take a dish with you for all to share for example:http://allrecipes.com/Recipe/Kosher-Style-Corned-B...

The only kosher flesh foods are from animals that chew the cud and have cloven hoofs, such as cattle, sheep, goats, and deer; the hindquarters must not be eaten. The only fish permitted are those with fins and scales; birds of prey and scavengers are not kosher. Moreover, the animals must be slaughtered according to ritual, without stunning, before the meat can be considered kosher. See also Passover.
